Abstract

Facilitating a signaling framework for configuring different types of reference signals for wireless communication systems is provided herein. A system can comprise: a processor; and a memory that stores executable instructions that, when executed by the processor, facilitate performance of operations. The operations can comprise: receiving a reference signal from a user equipment device; based on the reference signal generating a unique identifier from the reference signal; allocating a resource associated with the reference signal based on a reference signal type and a component carrier index list; associating the unique identifier with the resource, the component carrier index list, and the reference signal type in a data structure; and storing the data structure to the memory and transmitting the data structure to the user equipment device.

Claims (40)

1. A system, comprising:

a processor; and

a memory that stores executable instructions that, when executed by the processor, facilitate performance of operations, comprising:

generating a unique identifier associated with a reference signal resource;

allocating the reference signal resource with a type of reference signal and a list of index data representative of component carriers;

adapting the reference signal resource for use by a user equipment device;

transmitting the reference signal to the user equipment device; and

facilitating the user equipment device to measure the reference signal associated with the unique identifier;

wherein the unique identifier is generated as a function of a first identifier associated with the system, the reference signal type, and a second identifier associated with the user equipment device.

2. The system of claim 1 , wherein the facilitating further comprises using a quasi-colocation assumption for reference signal measurement.

3. The system of claim 1 , wherein the further facilitating further comprises using a reference symbol received power measurement for beam management.

4. The system of claim 1 , wherein the facilitating further comprises using a reference symbol received power measurement for mobility management.

5. The system of claim 1 , wherein the reference signal resource comprises a channel state information reference signal.

6. The system of claim 1 , wherein the reference signal resource comprises a phase-tracking reference signal.

7. The system of claim 1 , wherein the reference signal resource comprises a demodulation reference signal in an uplink transmission.

8. The system of claim 1 , wherein the reference signal resource comprises a demodulation reference signal in a downlink transmission.

9. A method, comprising:

generating, by a system comprising a processor, a unique identifier associated with a reference signal resource;

allocating, by the system, the reference signal resource with a type of reference signal and a list of index data representative of component carriers;

configuring, by the system, the reference signal resource for use by a user equipment device;

transmitting, by the system, the reference signal to the user equipment device; and

facilitating, by the system, the user equipment device to measure the reference signal associated with the unique identifier;

wherein the unique identifier is generated as a function of a first identifier associated with the system, the reference signal type, and a second identifier associated with the user equipment device.

10. The method of claim 9 , wherein the facilitating, by the system, further comprises using a quasi-colocation assumption for reference signal measurement.

11. The method of claim 9 , wherein the facilitating, by the system, further comprises using a reference symbol received power measurement for beam management.

12. The method of claim 9 , wherein the facilitating, by the system, further comprises using a reference symbol received power measurement for mobility management.

13. The method of claim 9 , wherein the reference signal resource comprises a demodulation reference signal in a downlink transmission.

14. A non-transitory machine-readable medium, comprising executable instructions that, when executed by a processor, facilitate performance of operations, comprising:

generating a unique identifier associated with a reference signal resource;

allocating the reference signal resource with a type of reference signal and a list of index data representative of component carriers;

configuring the reference signal resource for use by a user equipment device;

transmitting the reference signal to the user equipment device; and

facilitating the user equipment device to measure the reference signal associated with the unique identifier;

wherein the unique identifier is generated as a function of a first identifier associated with die processor, the reference signal type, and a second identifier associated with the user equipment device.

15. The non-transitory machine-readable medium of claim 14 , wherein the facilitating further comprises using a quasi-colocation assumption for reference signal measurement.

16. The non-transitory machine-readable medium of claim 14 , wherein the facilitating further comprises using a reference symbol received power measurement for beam management.

17. The non-transitory machine-readable medium of claim 14 , wherein the facilitating further comprises using a reference symbol received power measurement for mobility management.

18. The non-transitory machine-readable medium of claim 14 , wherein the reference signal resource comprises a channel state information reference signal.

19. The non-transitory machine-readable medium of claim 14 , wherein the reference signal resource comprises a phase-tracking reference signal.

20. The non-transitory machine-readable medium of claim 14 , wherein the reference signal resource comprises a demodulation reference signal in a downlink transmission.
